HYDROCARBON -BURNER.

SPECIFIGA TION forming part of Letters Patent No. 662,385, dated November 2'7, 1900.

To aZZ whom it may concern.-

Be it known vthat I, ALFRED A. ARNOTT, a citizen of the United States, residing at New Haven, in the county of New Haven and State of Connecticut, have invented certain new and useful Improvements in Hydrocarbon- Burners, of which the following is a specification, reference being had therein to the accompanying drawings.

My invention relates to improvements in hydrocarbon-burners; and its object is to improve the construction of the hydrocarbonburner invented by me and upon which Letters Patent of the United States No. 618,371 were issued the 24th day of January, 1899, by cheapening the cost of its manufacture and increasing its efficiency. This object is at- I tained by providing a vaporizing-tube with a reduced inlet end and embedding the same in a groove surrounding the body of the burner, thereby obviating the use of drilled holes of small diameter and great depth, by pro viding a casement to cover and protect the body portion of parts which fit telescopically within each other and which can be readily attached and detached, and by constructing the chimneysupport of but few parts, which are simple in design, which can be assembled economically and which can be readily placed over the body portion of the burner and rest upon rigid parts which will support it securely and firmly.

To these ends my invention consists of the hydrocarbon-burner having certain details of construction. and combination of parts, as will be hereinafter described, and more particularly pointed out in the claims.

Referring to the drawings, in which like numerals designate like parts in the several views, Figure 1 is a fragmentary vertical section of a burner constructed in accordance with myinvention as used in connection with a mantle of the Welsbach type. Fig. 2 is an elevation of the body member with the casement and chimney-su pport attached thereto. Fig. 3 is a plan View of the chimney'support. Fig. 4 is an elevation of the body member with the casement removed. Fig. 5 is a sectional plan view thereof upon line A 15 of Fig. 4. Fig. 6 is a sectional elevation of a portion of the inlet end of the vaporizingtube. Fig. 7 is an enlarged transversesectional elevation of the lower portion of the body member, and Fig. 8 is a fragmentary vertical section of a modified form of a burner constructed under my invention.

As previously made the oil-passages to the vaporizing-tube and the vapor-passage from the vaporizing-tube have been drilled in the casting forming the body member. These holes aresmall in diameter and of great depth, and hence mechanically are difficult and ex pensive to make, owing chiefly to the liability of the drill to run out ofits true center. Again, as the drills are of such small diameter in comparison to their length it requires skilled labor to operate them, and even with the most careful treatment and handling they frequently break. By the drilling process all of the corners in the passages must necessarily be square, which impairs very materially the efficiency of the burner, the square corners assisting in breaking up and thereby reducing the pressure of the oil and vapor. These disadvantages and many others I have attempted to overcome in my invention.

In the drawings the numeral 1 designates the body member, having the supply-pipe 2, connected therewith, the downwardly-projecting stem 8, and the horizontal arm 9, the bore 10 extending vertically through the center of the body member, with the hole ll of larger diameter at the upper end thereof.

The numeral 12 designates the vaporizingtube, connected at the inlet end with the supply-pipe 2 by means of passage 13 and which projects upwardly parallel with the axis of the body member nearly to the top of said body member, thence winding around the outside thereof, and thence projecting downwardly parallel with the'upwardly-projiecting portion to a point below the horizontal arm 9, whence it curves upwardly and enters the base of said arm concentric with the nipple 14:. The whole length of the said tube is embedded in a groove cast in the outside of the body member, thereby leaving no projecting parts. The inlet end 15 of the vaporizingtnbe is reduced in diameter, as shown in Fig. 6, to prevent the oil or vapor from being forced back through the said tube and into back pressure were created.

In my construction it will be noted that the groove in the body member obviates the use Of drilled e es a d y mak n al of th bends in the vaporizing-tube long and wellcurved I am enabled to maintain a constant unbroken pressure therein and a continuous unchecked'flow of oil and vapor thereth rough.

Resting loosely upon the top of the nipple 14 is a diaphragm or a check-plate 16, which consists of a thin metal plate having perforation l8 therethrough, the said plate being held rigid by the nut 17, which has a central hole 19 of larger diameter than the perforation in the said check-plate. The perforation 18 can be made of any desired diameter, the

- size beingdetermined by the amount of gas necessary to pass therethrough under a given,

pressure to furnish a light of the desired candle-power. It has been common hereto: fore to make the perforation in the nut 17, and thereby avoid the use of a check plate; but I find it much more convenient and economical to insert a check-plate which is of thin material, and therefore readily puncturable, while the nut 17 is of necessity made of much thicker material, and consequently a hole of such an extremely small diameter is not so readily drilled therethrough. As the check-plate is very inexpensive, a number of them with holes of varying diameters can be furnished with each burner, and the consumer can use the one best adapted for his particular locality or purpose.

The casement covering my burner consists of two cylindrical members or bands 20 2], ha g a l or eni 22 22 in one ide thereof to accommodate thesupply-tuhe 2. The band 20 is of larger diameter than the band 21 and is first placed over the Upper portion of the body member and at the same time covering the vaporizing-tube, the openn 22 a m tti h pp y-p p 2, a te which the band 21 is placed over the lower portion of the body member and is fitted telescopically upon the outside of the hand 20, as shown in Fig. 1 the opening 22 admiting t supply-pipe. As I ha e he pr iee par s 901; he bo y be 'i I e a l d he ve t sa by an asem t hieh is i y ipped Q and eff d whi can be made of simple design and manufactured at a sli ht cost. The chimney-support comprises a central hub 23, made of tubing of snfficient size to pass over the casement-band 2 0, the said hub resting upon the supply-pipe 2 when in its normal position,a gallery member 2%, having base portion 25, upon which the hi y S an e f ang po t 2 a tapped sleeve 27, mounted in the depending ie 28, a a. thum -sc e eeded W thin the said sleeve, a plurality of standards 30, hen-ally three i number, ig d y s eh ed at their lower ends to the central hub 23 and the end of the supply-tube.

by the thumb-screw 29,

In Fig. 8 I have shown a modified form of my burner in which the supply-pipe 2 is cast solid with a longitudinal groove therein, wh h groove e m ates h a the out en of the supply-pipe 2 in the hub 37, forming the oil-inlet. The vaporizing-tube 12 is extended from the body portion in this groove and through the hole 37, terminating in a contracted end, as shown in Fig. 6, flush with It is obvious that hy this construction I am enabled to entirely avoid the use of the central bore in the supply-pipe 2 and the passage 13 without affecting the operation of the device. For this reason and because of its reduced cost of man ufaethre I prefe in m ta ees t u this modified form of burner,
